Description

The present invention relates to a delivery container for stick-shaped cosmetics and the like.

As a conventional feeding container, as described in Patent Document 1, a container body, a spiral tube which is fitted into the container body so as not to rotate and cannot move in the axial direction, and a spiral cylinder provided with a female thread portion on the inner circumference, and a container. It is provided with a fitting cylinder portion that is inserted into the main body and is rotatably and axially immovably fitted to the outer periphery of the spiral cylinder, and an operation cylinder portion that extends upward from the fitting cylinder portion. A rotary operation cylinder, a middle plate portion that is stopped from rotating inside the operation cylinder portion of the rotary operation cylinder and is stored so as to be able to move up and down, and a female screw portion of a spiral cylinder that extends downward from the lower surface of the bottom of the middle plate portion. Some have a middle plate body provided with an operating shaft portion that is screwed into the middle plate body, and rod-shaped contents held in the middle plate portion of the middle plate body are housed in the operation cylinder portion of the rotation operation cylinder.

In this feeding container, by rotating the container body and the spiral cylinder with respect to the rotation operation cylinder, the spiral cylinder fitted in the container body and the operating shaft portion of the inner plate body are screwed into each other, and the inner plate body is screwed. The inner plate portion is moved up and down in the operation cylinder portion of the rotation operation cylinder, and the rod-shaped contents held in the inner plate portion are extended or lowered from the operation cylinder portion so that they can be used.

At this time, at the upper end of the inner circumference of the fitting cylinder portion in the rotation operation cylinder of the feeding container, the non-circular outer circumference of the operating shaft portion in the inner plate body rotates with the spiral cylinder as the spiral cylinder rotates. In the direction, a non-circular detent hole is formed that is engageably inserted. As a result, the rotation of the inner plate can be regulated, and the inner plate portion of the inner plate can be moved up and down without rotating.

However, in this feeding container, the molten agent is directly poured into the inner circumference of the operation cylinder portion of the rotary operation cylinder and the middle plate portion of the inner plate body to form the above-mentioned rod-shaped contents. In some cases, the rod-shaped contents held in the inner plate portion of the inner plate body are closely adhered to the operation cylinder portion of the rotary operation cylinder without a gap, or are stored through a minute gap. In this case, when the rod-shaped contents are carried down, the rod-shaped contents are attached to the inner circumference of the operation cylinder portion of the rotary operation cylinder, and the middle dish portion holding the lower end side of the rod-shaped contents is the rod-shaped contents. When a tensile force is applied to the rod-shaped contents, the rod-shaped contents may be pulled in the intermediate direction in the axial direction and broken.

On the other hand, in the feeding container described in Patent Document 2, the rod-shaped contents are described above by restricting the rotation direction of the rotating operation cylinder with respect to the container body and adopting a ratchet mechanism for preventing the rod-shaped contents from being carried down. We are trying to prevent breakage that may occur when moving down.

However, the non-retractable feeding container using the ratchet mechanism described in Patent Document 2 has a disadvantage that when the rod-shaped contents are excessively fed, the rod-shaped contents cannot be returned into the operation cylinder portion of the rotary operation cylinder.

Therefore, in the pay-out container that can be carried down, the screw pitch of the female screw portion provided on the inner circumference of the spiral cylinder screwed to the operating shaft portion of the inner plate body is reduced in order to prevent the rod-shaped contents from breaking when being carried down. It is conceivable to prevent the rod-shaped contents from breaking by slowing down the rod-shaped contents.

However, when the screw pitch of the female screw portion provided on the inner circumference of the spiral cylinder is reduced, when the rod-shaped content is carried down to the carry-down end, the operating shaft portion of the inner plate body that has reached the bottom dead point with respect to the spiral cylinder is affected. A large torque in the rotational direction that accompanies the rotation with the spiral cylinder acts, and the non-circular outer circumference of the operating shaft portion of the inner plate body is formed at the upper end of the inner circumference of the fitting cylinder portion of the rotary operation cylinder. It becomes easy to overrun until it bites into the hole surface of the detent hole. The phenomenon that the non-circular outer circumference of the inner plate bites into the non-circular detent hole on the side of the rotation operation cylinder is caused by the fact that the constituent material of the inner plate (for example, PP resin) is different from the constituent material of the rotation operation cylinder (for example, ABS resin). It is soft and is caused by the non-circular outer peripheral corners and the like of the inner plate body hitting the hole surface of the non-circular detent hole on the side of the rotary operation cylinder to be dented, deformed, or scraped. The operating shaft of the inner plate that strongly bites into the detent hole on the side of the rotation operating cylinder becomes difficult to rotate in the feeding direction of the rod-shaped contents by eliminating the biting, and the rod-shaped contents are re-rolled out. There is a problem that it becomes difficult.

An object of the present invention is the occurrence of overrun in a feeding container that allows the rod-shaped contents to be fed and carried down, in which the inner plate body that has been carried down to the carrying-out end of the rod-shaped contents bites into the detent hole on the side of the rotary operation cylinder. It is to make it suppressable.

The invention according to claim 1 is inserted into the container body, a spiral cylinder that is non-rotatably and non-movably fitted in the container body and has a female screw portion on the inner circumference, and the container body. At the same time, a rotary operation cylinder having a fitting cylinder portion that is rotatably and non-movably fitted to the outer periphery of the spiral cylinder and an operation cylinder portion that extends upward from the fitting cylinder portion, and rotation. The middle plate part that is prevented from rotating inside the operation cylinder part of the operation cylinder and is stored so that it can move up and down, and the operating shaft part that extends downward from the lower surface of the bottom of the middle plate part and is screwed into the female screw part of the spiral cylinder. At the upper end of the inner circumference of the fitting cylinder portion in the rotary operation cylinder, the non-circular outer circumference of the operating shaft portion in the middle plate body is spiraled with the rotation of the spiral cylinder. A non-circular detent hole that is inserted so that it can be engaged with the cylinder in the spiral direction is formed, and the rod-shaped contents held in the middle plate portion of the inner plate body are stored in the operation cylinder portion of the rotary operation cylinder. A feeding container that enables the rod-shaped contents to be fed or lowered by feeding and rotating the container body and the spiral cylinder with respect to the inner plate body, and is provided with the female screw portion of the spiral cylinder. The portion is provided with a slit that penetrates the wall thickness and intersects the thread of the female screw portion.

According to the present invention, in a feeding container that allows the rod-shaped contents to be fed and carried down, an overrun occurs in which the inner plate body carried down to the carrying-out end of the rod-shaped contents bites into the detent hole on the side of the rotary operation cylinder. Can be suppressed.

An engaging recess 12 is formed to be engaged.

As shown in FIG. 5, the spiral cylinder 20 is fitted in the container body 10 so as not to rotate and cannot move in the axial direction, and a female screw portion 25 is provided on the inner circumference.

That is, on the outer periphery of the spiral cylinder 20, an engaging convex portion 21 that engages with the engaging concave portion 31 of the rotary operation cylinder 30 is formed in the upper end side intermediate portion, and the engaging convex portion 21 of the container body 10 is formed in the lower end side intermediate portion. An engaging convex portion 22 that engages with the concave portion 12 is formed, and an outward knurled portion 23 that engages with the inward knurled portion 11 of the container body 10 is formed at the lower end portion. A flange portion 24 that supports the lower end surface of the rotation operation cylinder 30 is further formed between the engaging convex portion 21 and the engaging convex portion 22 on the outer circumference of the spiral cylinder 20.

Further, a female screw portion 25 for screwing with the inner plate body 40 is provided at the upper end portion of the inner circumference of the spiral cylinder 20 within a range of a length a from the upper end.

As shown in FIG. 7, the rotation operation cylinder 30 is fitted to the fitting cylinder portion 30A which is inserted into the container body 10 and is rotatably and axially immovably fitted to the outer circumference of the spiral cylinder 20. It includes an operation cylinder portion 30B that extends upward from the cylinder portion 30A and is operated by being gripped by a finger or the like.

That is, an engaging concave portion 31 that rotatably engages with the engaging convex portion 21 of the spiral cylinder 20 is formed in the lower portion of the inner circumference of the fitting cylinder portion 30A in the rotation operation cylinder 30.

Here, a non-circular detent hole 32 is formed at the upper end of the inner circumference of the fitting cylinder portion 30A in the rotation operation cylinder 30. That is, a pair of restricting plates 33 that face each other in a line symmetry with one diameter line of the fitting cylinder portion 30A are provided, and the linear portions 33A of both regulating plates 33 and the regulating plates of the fitting cylinder portion 30A are provided. The track-shaped elliptical opening surrounded by the inner peripheral surface other than 33 is the detent hole 32 described above.

As shown in FIG. 8, the inner plate body 40 is stored in the operation cylinder portion 30B of the rotary operation cylinder 30 so as to be vertically movable, and the inner plate portion 40A from the lower surface of the bottom portion 41 of the middle plate portion 40A. It is provided with an operating shaft portion 40B extending downward and screwing into the female thread portion 25 of the spiral cylinder 20.

A non-circular outer circumference 42 is formed on the outer circumference of the operating shaft portion 40B in the middle plate 40. That is, in the present embodiment, a pair of arcuate portions 42A that face each other in a line symmetry with one diameter line of the operating shaft portion 40B in between, and a pair of straight line portions 42B that connect the ends of the arcuate portions 42A. The outer circumference of the track-shaped ellipse made of the above is the above-mentioned outer circumference 42. Then, on the outer circumference of the arc portion 42A on the outer circumference 42 of the operating shaft portion 40B, a lower end male threaded convex portion 43 screwed into the female threaded portion 25 of the spiral cylinder 20 and extending over a range of about one circumference from the lower end. A male threaded portion 44 is provided extending from the upper end of the male threaded convex portion 43 to the vicinity of the upper end from a position via a length b equal to or longer than the length a of the female threaded portion 25. An idling space portion 45 having a length b is formed between the threaded convex portion 43 and the male screw portion 44 on the outer circumference of the arc portion 42A.

In this way, at the time of assembling the inner plate body 40 to the rotation operation cylinder 30, the non-circular outer peripheral 42 of the operating shaft portion 40B in the inner plate body 40 becomes the spiral cylinder 20 accompanying the rotation of the spiral cylinder 20. It is engageably inserted into the non-circular detent hole 32 formed at the upper end of the inner circumference of the fitting cylinder portion 30A in the rotation operation cylinder 30 in the rotating direction of the above. As a result, the inner plate body 40 can be stored in the operation cylinder portion 30B of the rotation operation cylinder 30 so as to be prevented from rotating and vertically movable.

However, in the feeding container 100, as shown in FIG. 5, the thickness of the spiral cylinder 20 is penetrated through the cylinder portion 20T provided with the female screw portion 25, and the thread of the female screw portion 25 is threaded. A slit 26 is provided that intersects with the.

In the present embodiment, the slits 26 provided in the spiral cylinder 20 are provided at a plurality of locations in the circumferential direction of the tubular portion 20T in the spiral cylinder 20. The slits 26 are provided at two positions on the spiral cylinder 20 that are located on the same diameter of the cylinder portion 20T.

The slit 26 provided in the spiral cylinder 20 has an elongated hole shape in the present embodiment. Then, both ends of the elongated hole-shaped slit 26 are closed within the range of the tubular portion 20T in the spiral cylinder 20, and are not opened to the outside.

Specifically, the slits 26 provided in the spiral cylinder 20 are provided at two positions that are located on the same diameter of the tubular portion 20T in the spiral cylinder 20. Further, each slit 26 has a width along the circumferential direction of the tubular portion 20T as K, a length along the axial direction of the tubular portion 20T as L exceeding the screw range a of the female thread portion 25, and a direction along the axial direction of the tubular portion 20T. It is extended (can be obliquely crossed in the axial direction), and both ends of the slit 26 are extended within the range of the tubular portion 20T and outside the thread range a of the female thread portion 25 as described above. ing.

In the spiral cylinder 20, the female screw portion 25 provided on the cylinder portion 20T is preferably a round screw having an arcuate cross section.

In the feeding container 100 of the present embodiment, the container body 10, the spiral cylinder 20, and the rotation operation cylinder 30 are molded from a relatively hard resin material such as ABS resin, and the inner plate body 40 is relatively formed of PP resin or the like. It is preferable to mold from a soft resin material. By forming the inner plate body 40 from a relatively soft resin material, the screw sliding property between the inner plate body 40 and the spiral cylinder 20 is ensured, the molding stability of the inner plate body 40 is improved, and the cost is reduced. Can be realized.

Hereinafter, the procedure for assembling the feeding container 100 will be described.
(1) The spiral cylinder 20 is inserted into the container body 10, and the inward knurled portion 11 of the container body 10 and the outward knurled portion 23 of the spiral cylinder 20 are engaged with each other, and the engaging concave portion 12 and the engaging convex portion 22 are engaged. By engaging the spiral cylinder 20, the spiral cylinder 20 is fitted into the container body 10 so as not to rotate and to move in the axial direction.

(2) Insert the inner plate body 40 from above the rotation operation cylinder 30. At this time, the lower end of the non-circular outer circumference 42 of the operating shaft portion 40B of the inner plate body 40 is inserted into the non-circular detent hole 32 of the rotation operation cylinder 30, and the container body 10 and the spiral cylinder 20 are viewed from above. While rotating clockwise, the lower end male threaded convex portion 43 of the operating shaft portion 40B of the inner plate body 40 is screwed into the female threaded portion 25 of the spiral cylinder 20. As a result, the spiral cylinder 20 rotates and rises with respect to the inner plate body 40, and eventually, the female screw portion 25 of the spiral cylinder 20 and the lower end male screw-shaped convex portion 43 of the inner plate body 40 are screwed together. The female screw portion 25 is located in the idling space portion 45 of the inner plate body 40.

(3) When the container body 10 and the spiral cylinder 20 are further rotated, the threaded portion 44 of the inner plate body 40 is screwed into the female threaded portion 25 of the spiral cylinder 20, and the spiral cylinder 20 rotates with the inner plate body. Ascending with respect to 40, the upper end of the spiral cylinder 20 is inserted into the inner circumference of the fitting cylinder portion 30A of the rotation operation cylinder 30.

(4) Finally, the engaging convex portion 21 at the upper end side intermediate portion of the spiral cylinder 20 engages with the engaging concave portion 31 of the fitting cylinder portion 30A of the rotating operating cylinder 30, and the fitting cylinder of the rotating operating cylinder 30. The lower end surface of the portion 30A abuts on the flange portion 24 of the spiral cylinder 20, the rotation of the spiral cylinder 20 with respect to the rotation operation cylinder 30 and the inner plate 40 is stopped, the ascending due to screwing is also stopped, and the feeding container 100 Assemble.

At this time, as shown in FIG. 1, the middle plate portion 40A of the inner plate body 40 is near the lower end of the inner circumference of the operation cylinder portion 30B of the rotary operation cylinder 30, and the female screw portion 25 of the spiral cylinder 20 is the inner plate body. It is fixed near the upper end of the threaded portion 44 of the operating shaft portion 40B of 40.

(5) The molten agent of the rod-shaped contents is directly poured into the operation cylinder portion 30B of the rotary operation cylinder 30 and the middle plate portion 40A of the inner plate body 40 to be formed. As a result, the feeding container 100 is formed in which the rod-shaped contents held in the inner plate portion 40A of the inner plate body 40 are stored in the operation cylinder portion 30B of the rotation operation cylinder 30.

The lid 50 is attached to the container body 10 constituting the feeding container 100, and the lid is closed.

In the feeding container 100, after removing the lid 50 from the container main body 10, the container main body 10 and the spiral cylinder 20 are viewed from above and rotated counterclockwise in the feeding rotation direction, whereby the female screw portion 25 of the spiral cylinder 20 is formed. By screwing the inner plate body 40 with the screw portion 44, the inner plate body 40 is raised in the rotation operation cylinder 30, and the rod-shaped contents held in the inner plate body 40 are operated by the rotation operation cylinder 30. It can be used by feeding it out from the cylinder portion 30B.

By rotating the container body 10 and the spiral cylinder 20 to the right in the downward rotation direction when viewed from above, the inner plate body 40 is lowered in the rotation operation cylinder 30 and the rod-shaped contents held in the inner plate body 40 are rotated. It can be carried down and stored in the operation cylinder portion 30B of the operation cylinder 30.

The rod-shaped contents are repeatedly fed by rotating the container body 10 and the spiral cylinder 20 counterclockwise to further raise the inner plate 40 with respect to the rotation operation cylinder 30 and the spiral cylinder 20, and the female screw portion of the spiral cylinder 20. When the screw between the 25 and the threaded portion 44 of the inner plate body 40 is disengaged and the female threaded portion 25 enters the idling space portion 45 of the operating shaft portion 40B, the female threaded portion 25 idles with respect to the operating shaft portion 40B. , The middle plate 40 does not rise. Since the length b of the idling space portion 45 is larger than the length a of the female screw portion 25, even if the container body 10 and the spiral cylinder 20 are rotated counterclockwise, the female screw portion 25 continues to idle and is in the middle. It is possible to prevent the dish body 40 from coming off from the spiral cylinder 20 and the rotation operation cylinder 30.

Therefore, according to the present embodiment, the following effects are obtained.
(a) In the feeding container 100, the cylindrical portion 20T of the spiral cylinder 20 provided with the female threaded portion 25 is provided with a slit 26 that penetrates the wall thickness and intersects the thread of the female threaded portion 25. .. As a result, when the inner plate body 40 and the rod-shaped contents are carried down to the carry-down end by the rotation operation of rotating the container body 10 and the spiral cylinder 20 clockwise when viewed from above in the carry-down rotation direction, the spiral cylinder 20 is carried down to the carry-down end. The non-circular outer circumference 42 of the inner plate body 40 that rotates with the carry-down rotation hits the hole surface of the non-circular detent hole 32 of the rotation operation cylinder 30, and the inner plate body 40 reaches the bottom dead point with respect to the spiral cylinder 20. Then, when the spiral cylinder 20 tries to lower the inner plate 40 further from the bottom dead point, the spiral cylinder 20 hits the detent hole 32 of the rotation operation cylinder 30 and is detented. The rotation is stopped by. Therefore, the spiral cylinder 20 to which the torque in the rotation direction is further applied cannot rotate around the inner plate body 40, and the slit 26 provided in the cylinder portion 20T is expanded in the circumferential direction of the cylinder portion 20T. The spiral cylinder 20 is opened, and the diameter of the spiral cylinder 20 is expanded to idle around the inner plate body 40.

At this time, the female screw portion 25 of the spiral cylinder 20 to which the rotational torque is further applied by further rotating the container body 10 and the spiral cylinder 20 to the right in the downward rotation direction when viewed from above is shown in FIGS. 11A to 11A. As shown in (C), the spiral cylinder rides on the male screw portion 44 provided on the operating shaft portion 40B of the inner plate body 40 whose rotation is restrained, and further, as shown in FIGS. 11 (D) to 11 (F). The spiral cylinder 20 is rotated once by overcoming the male threaded portion 44 while accompanied by the above-mentioned expansion deformation of the cylinder portion 20T of 20 and the diameter reduction deformation of the working shaft portion 40B of the inner plate body 40, for example, the hollow portion 46. Let it spin for a minute. After the above-mentioned idling of the spiral cylinder 20, the internal plate body 40 which has been overcome by the female screw portion 25 of the spiral cylinder 20 by one rotation of the male screw portion 44 has the male screw portion 44 as shown in FIG. 11 (F). By raising the screw pitch (about 1 mm) corresponding to one rotation of the above in the axial direction, the distortion of the diameter-expanding deformation of the spiral cylinder 20 and the diameter-reducing deformation of the operating shaft portion 40B in the middle plate 40 is eliminated. Therefore, it is possible to prevent the overrun in which the non-circular outer peripheral 42 on the side of the inner plate 40 bites into the non-circular detent hole 32 on the side of the rotation operation cylinder 30.

(b) The screw pitch of the female screw portion 25 provided on the inner circumference of the spiral cylinder 20 screwed to the operating shaft portion 40B of the inner plate body 40 is reduced, and the carrying-down speed of the rod-shaped contents is slowed down. In the feeding container that can prevent the breakage that may occur when the rod-shaped contents are carried down, a large rotational torque acts on the operating shaft portion 40B of the countersunk body 40 that has reached the bottom dead point with respect to the spiral cylinder 20 due to its machine screw pitch. Even when this is possible, it is possible to suppress the occurrence of overrun in which the non-circular outer peripheral 42 on the side of the inner plate 40 bites into the non-circular detent hole 32 on the side of the rotary operation cylinder 30 according to the above (a).

As a result, in the pay-out container that can be carried down, it is possible to prevent the occurrence of overrun in which the inner plate body 40 bites into the detent hole 32 on the side of the rotation operation cylinder 30 while preventing the occurrence of breakage of the rod-shaped contents at the time of carrying down. ..

(c) Slits 26 provided in the spiral cylinder 20 are provided at a plurality of locations in the circumferential direction of the tubular portion 20T in the spiral cylinder 20. As a result, it is possible to facilitate the expansion of the slit 26 in the above-mentioned (a) and to ensure that the spiral cylinder 20 slips.

(d) The slit 26 provided in the spiral cylinder 20 has an elongated hole shape. As a result, it is possible to facilitate the expansion of the slit 26 in the above-mentioned (a) and to ensure that the spiral cylinder 20 slips.

(e) Both ends of the elongated slit 26 provided in the spiral cylinder 20 are closed within the range of the tubular portion 20T in the spiral cylinder 20 and are not opened to the outside. As a result, after the slit 26 is expanded and the diameter of the spiral cylinder 20 is expanded by the rotational torque applied to the spiral cylinder 20 in (a) above, the spiral cylinder 20 is deformed to expand its diameter. It is possible to smoothly realize elastic restoration of the enlarged diameter deformation without permanently deforming the spiral cylinder 20, and it is possible to secure the stability of the feeding or lowering function of the rod-shaped contents by the rotation of the spiral cylinder 20.

(f) The thread of the female thread portion 25 of the spiral cylinder 20 is made of a round screw having an arcuate cross section. As a result, the female threaded portion 25 of the spiral cylinder 20 to which the torque in the rotational direction is further applied rides on the male threaded portion 44 provided on the operating shaft portion 40B of the inner plate body 40, and when the female threaded portion 44 is further overcome, it is easy to overcome the screw portion. Can be achieved. Further, it is possible to suppress the occurrence of scratches and wear on the threaded surfaces of the female threaded portion 25 of the spiral cylinder 20 and the threaded portion 44 of the inner plate body 40 which is the overcoming partner thereof.

(g) When the rod-shaped content is formed by directly pouring the molten agent into the inner circumference of the operation cylinder portion 20T of the rotation operation cylinder 30 and the middle plate portion 40A of the inner plate body 40, the inner plate body The rod-shaped contents held in the inner plate portion 40A of the 40 are housed in the operation cylinder portion 20T of the rotation operation cylinder 30 in close contact with each other without any gap. Therefore, in a feeding container in which the rod-shaped contents are liable to be broken at the time of lowering due to the close contact, the screw pitch of the female screw portion 25 provided on the inner circumference of the spiral cylinder 20 can be reduced as described in (b) above. Preventing the rod-shaped contents from breaking during carrying down, and suppressing the occurrence of overrun in which the non-circular outer peripheral 42 on the side of the inner plate 40 bites into the non-circular detent hole 32 on the side of the rotary operation cylinder 30. The effect of is remarkable.

As shown in FIG. 6, the elongated slit 26 provided in the spiral cylinder 20 of the present invention may have one end extending to the upper end of the cylinder 20T and being opened to the outside.

Further, the slit 26 provided in the spiral cylinder 20 of the present invention may have a width K along the circumferential direction of the operation cylinder portion 20T set to zero, a minute gap, or the like.

Further, in the inner plate body 40 applied to the present invention, in the above-mentioned (a), the expansion of the tubular portion 20T provided with the slit 26 in the spiral tubular portion 20 while avoiding the reduced diameter deformation of the hollow portion 46 with respect to the operating shaft portion 40B. In order to stabilize the diameter deformation, as shown in FIG. 9, the spiral cylinder 20 is fitted in the axial direction on the upper end side of the operating shaft portion 40B lowered to the carry-down end with respect to the container body 10 and the spiral cylinder 20. It is preferable that the range c in which the threaded portion 25 is screwed is the solid portion 47.

According to the present invention, in a feeding container that allows the rod-shaped contents to be fed and carried down, an overrun occurs in which the inner plate body carried down to the carrying-out end of the rod-shaped contents bites into the detent hole on the side of the rotary operation cylinder.
